The main thing that put me off Java was not so much the fact that
you're restricted to OOP and that it's verbose etc., but that it
caused all sorts of problems when shipping the actual programs.
"Write once run everywhere" is a myth, if you ask me. D is much
closer to that than Java. In the end we encountered so many
problems that I dumped Java for cross platform development (and
for development in general). Nobody in the Java world ever talks
about this, but cross platform doesn't really work (apart from
running simple programs).

Java is not really an object-oriented programming language. OK it has
classes, inheritance, and method calls, but it is not founded on message
passing. For example:
a + b
is not a message in Java as it is in C++, Python, etc.
Since when does C++ does support message passing?
Write Once Run Anywhere (WORA) has been a known fallacy since about
1995 ;-) Versions of things really are a bit of a
dependency/configuration nightmare. Maven Central and Gradle help
somewhat for the JVM, but then there is the shared library nightmare for
all other platforms.
It is surely way better than the alternatives, specially if one
remembers the chaos of writing portable code in C or C++ back when Java
apperead.
On those days I was writing "portable" code across UNIX systems and
discovering that POSIX isn't as portable as it gets sold by. The real
fun was between the K&R C, ANSI C and pre-standard C++ support across
compilers.
